SPECIFICATION forming part of Letters Patent No. 706,761, dated August12, 1902. Application tiled January 2, 1902. Serial No. 88,112- (N'omodel.)

To a, whom it may concern.

Be it known that I, JOHN G. KOEGLE, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in GasBurners, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

This invention has for its object to provide a gas-burner moreparticularly intended for use with heating-stoves and grates havingasbestos backs, but also adapted for other uses, and which while ofsimple construction, so that it may be cheaply manufactured, will beconvenient, durable, and efficient in use.

To this end the improved burner comprises a cast-metal body, integralwith and depending from which is a frusto-conical orinverted-funnel-shaped mixing-chamber having a suitable opening orhollowplug for attachment to a gas-pipe and suitable side openings for theadmission of air. -Within the chamber of the burner, above theinlet-opening from the mixing-chamber, is a'horizontal spreader, againstwhich the ascending mixture of air and gas, which is compressed as itrises in the inverted-funnel-shaped mixing-chamber, strikes with someforce, so as to be evenly distributed within and to quickly fill thechamber of the burner. The upper portion of the elongated body of theburner is contracted so as to be approximately frustoconical incross-section, with a reduced upwardly-extending part or ridge in whichthe burner-openings areformed.

The burner may be cast in one piece by proper coring or may be formed intwo or more pieces, the adjacent edgesof which will be properly smoothedand the parts of which can be secured together by bolts. The body of theburner is preferably provided at its ends with circular supports havingbeveled or undercut edges to be engaged by lips on suitable holders, inwhich the burners maybe pivotally mounted, so that they may be adjustedto give them any desired slant or inclination relative to the backs ofthe stoves or grates in which they are mounted.

Referring to the drawings,Figure l is a plan view of the improvedburner; and Fig. 2, an elevation of the same, partly in verticalslightly-modified form of burner.

section. Fig. 3 is a central vertical transverse section of the burnershown in Figs. 1 and 2, and Fig. 4 is a similar section of a Fig. 5 is aside view of one form of my burner having two inlet and mixing chambers.

Referring to the drawings, a denotes the body of the burner, which maybe cast in a single piece properly cored out, and b is a frusto-conicalor inverted-funnel-shaped mixing-chamber depending from the body a at orabout midway of its length andpreferably formed integral with said body.The chamber 1) is provided near its base with side openings 0 for theadmission of air and with a gas-opening d, with which a suitable gaspipemay be placed in communication, either by means of a plugc or otherwise.

Above the inlet or upper end of the mixing-chamber 19, within thechamber of the body of the burner, is provided a spreader f, consistingof a horizontal transverse web or plate of suitable length to deflectthe upwardlyrising mixture of air and gas outward toward theburner-openings h are formed either by casting or drilling.

The body of the burner is preferably provided at its ends with circularundercut lugs or projections 7a to serve as journals or supports for theburner, said lugs or projections being of suitable form to be engaged byinturned flanges or lips on holders 2', in which the burners may bemounted. By making the supports 70 circular the burners may be partiallyturned in their supports 't'to give them any desired slant orinclination in mounting them in place in the stove or grate. It will beunderstood, however, that these sup ports at the ends of the burnersneed not necessarily be circular, but might be square or of otherpolygonal form, if it be not desired to mount the burners in such a waythat they can be turned in their mountings. These end supports, whileconvenient, are not tapering construction.

essential, as the improved burner may be and gas will be compressed asit rises, the

ascending volume of-air and gas will issue into the chamber in the bodyof the burner with considerable force and as it comes in contact withthe spreader will be deflected toward the outer ends of the saidchamber, also causing the pressure within the chamber of the burner tobe as nearly uniform as possible. Also by forming the interior upperportion of the body of the burner upwardly tapering inwardly on curvedlines in the manner shown, so as to form a reduced longitudinal ridge atthe top of the burner and in which the burner-openings are provided, thecombustible mixture of air and gas will be somewhat compressed as itrises and will issue from the burner-openings with more force than wouldotherwise occur, and thus a better burning effect in the gas-jets willbe produced.

The improved cast-metal burner is strong and durable and may be cheaplymanufactured and by being all made in one, or at most very few parts, isso simple that liability of getting out of order or of losing orbreaking any parts is reduced to a minimum.

My improved burner may, if desired, be provided with more than one inletand mixing chamber 1). Fig. 5 shows one of my burners having twofrusto-conical inlet and mixing chambers, and for very long burners moremight be provided.

1 have demonstrated by practical tests that the curved-lineupwardly-tapering interior chamber of the body of my improved burner isimportant, in that it causes such a thorough mixing or commingling ofthe ascending volume of air and gas coming together from the twoopposite sides of the burner so that I am enabled by this constructionto secure a much better burningrcsult or effect than can be secured by aburner the upper part of which is simply rounded or curved interiorly incross-section, owing, as nearly as I have been able to discover, to thecompressed commingling effect resulting from my upwardly- I do not,however, wish to be understood as limiting my invention to the exactupwardly-tapering construction of the body of the burner herein shown orto the exact construction shown for the inlet and mixing chamber orchambers.

Having thus described my invention, I claim and desire to secure byLetters Patent- 1. A burner consisting of an elongated hollow body theinterior upper portion of which tapers upwardly, on curved lines, toform a reduced longitudinal ridge which is provided with a row or seriesof burner-openings; whereby as the combustible mixture within the burnerascends in the chamber thereof it will be compressed and caused to issuefrom said burner-openings with more force than would otherwise occur;said burner-body having at its lower part one or more dependingfrusto-conical mixing-chambers into which the gas is conducted, saidmixing-chambers being each provided, near its base, with side openingsfor the admission of air; and the said burner-body having, above theinlet of each mixing-chamber, a baffle-plate, f, to equalize thepressure of the combustible gaseous mixture within the chamber of thesaid burner.
